Did a full install of BETA2, and rebooted.
A process called "cannaserver" was running as root, and listening on a TCP
socket :-(
This is obviously very dangerous.
I fully expect to find specific security issues with "cannaserver". I'll
update the bug tomorrow if I get time to take a look.

Hmm - well, I haven't yet had the time to look at "cannaserver"
However, surprise surprise, Canna just got a few mentions on bugtraq for a
remotely exploitable problem (Debian have issued a security update).
Looks like "cannaserver" is as big a potential security disaster as "jserver"
